In geometry, the elongated pentagonal gyrocupolarotunda is one of the Johnson solids (J41). As the name suggests, it can be constructed by elongating a pentagonal gyrocupolarotunda (J33) by inserting a decagonal prism between its halves. Rotating either the pentagonal cupola (J5) or the pentagonal rotunda (J6) through 36 degrees before inserting the prism yields an elongated pentagonal orthocupolarotunda (J40).
The 92 Johnson solids were named and described by Norman Johnson in 1966.

Famous quotes containing the word elongated:
“Neighboring farmers and visitors at White Sulphur drove out occasionally to watch ‘those funny Scotchmen’ with amused superiority; when one member imported clubs from Scotland, they were held for three weeks by customs officials who could not believe that any game could be played with ‘such elongated blackjacks or implements of murder.’”
